docker: ironic-api starts both API and PXE services

[Dan Prince]

The Ironic PXE service container fails to startup correctly due to a port conflict. It appears that when we cut Ironic API over to use HTTP that container is now trying to start both apache services.

The fix should be to use unique "config" root filesystems for each service thus preventing the Apache services in each container from trying to start each others conf.d files.

    Fix ironic-pxe startup issues

    This patch updates the ironic-api docker service so that it
    generates its config files in a unique config root. This
    ensures that it doesn't have config files in the httpd
    conf.d directory for both the API and PXE services thus
    causing the API container to attempt to launch both of them.

    This functionally fixes the Ironic API and PXE services with
    docker so they once again can bring up an overcloud.
